Compare any two graphics cards:
Radeon HD 4730 vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 4730 features a core clock speed of 700 MHz and a GDDR5 memory speed of 900 MHz. It also features a 128-bit bus, and uses a 55 nm design. It is comprised of 640(128x5) SPUs, 32 TAUs, and 8 ROPs.Compare those specs to the Radeon HD 6570 (OEM) 2GB, which features GPU core speed of 650 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also features 480 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6570 (OEM) 2GB should theoretically be a bit superior to the Radeon HD 4730 overall. (explain)
Texel RateThe Radeon HD 4730 should be quite a bit (more or less 44%) better at AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe Radeon HD 4730 should be just a bit (approximately 8%) better at anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and also will be capable of handling higher resolutions without slowing down too much. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
